Favorite gauge of VS NATURAL GUT

Babolat VS Natural ThermoGut 15L Touch

Babolat VS Natural ThermoGut 16 Touch

I have decided to order 3 sets of Babolat VS gut . I would like to know whether I should buy 2 16g and 1 15L string or vice-versa. I would also appreciate comments on the difference between the 15L gauge and the 16 gauge. Thanks

If you go for VS, then you need to at least try the 17. The biggest difference between VS and Tonic is that VS is the only one to offer it in 17. My rec, therefor, would be for one set of VS 17, one set of Tonic 16 and one set of VS 16. See if you can tell the difference between Tonic and VS 16. If you can't... then you know what you should buy in the future to save yourself some mullah.
